1 Claim.

'I'he object of my invention is to provide a device of simple, durable and inexpensive construction that may be readily, quickly and easilyapplied to a toilet seat or the like for the purpose of forcing a current of air from the interior of the toilet outwardly to a point of discharge preferably on the exterior of a building for preventing odors from the toilet from escaping into the room in which the toilet is locatedand whereby the toilet may be deodorized mechanically without the use of chemicals.

.Another object is to provide mechanically operated means whereby an electric motor for forcing air through the air conductor pipe to a point of discharge may be automatically started by the weight of an operator upon the toilet seat.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawing, in which:

Figure 1 shows a top or plan view with parts broken away illustrating an ordinary toilet having my improvement applied thereto, taken on the line '1-1 of Figure 2.

Figure 2 shows a side elevation of same partly in section.

Figure 3 shows an enlarged detail plan view of the intake nozzle portion of my improvement.

Figure 4 is a sectional view of same on the line 4 4 of Figure 3.

' Referring to the accompanying drawing, I have used the referencenumeral 10 to indicate a toilet bowl of ordinary construction. Y These bowls are usually provided with water inlet openings, and these 4openings preferably have downwardly extended iianges over their inner ends. On top of.

the bowl is the usual hinged seat 13 and hinged cover 14. 'For providing a hinged connection between the seat 13 and-the bowl there is usually employed bolts 15 having washers 16 above the bowl.

In the form of the invention illustrated in Figures 1, 2, 3, and 4 my improvement comprises a f sheet metal nozzle indicated generally by the numeral 17, and having at its inlet end a narrow horizontal slot 18 with the material at the upper end of the slot projecting over the material at the bottom ofthe slot, asshown in Figure 4, to prevent liquids from above entering the slot.

At theouterendofthe nozzleisaroundedpipe member 19 connected by an elbow 20 with a pipe 21 leading to a compartment 22, in which thereiseontained an electric motor 23 and a fan 24, or other means for causing an aircurrent to liow upward- 1ythroughthepipe20 ortocreateapartialvacuum within the compartment 22. This compartw 'ment 22 is provided with a Pipe 25 preferably leading to a point ot discharge outside of -the building in which the toilet is located.

0n the sides of the nozzle 17 are the outwardly extended flanges 26, and these flanges can be. placed upon the top of the bowl and extended under the washer 16 sothat by tightening up the bolts on said washer, the nozzle may be adjustably clamped to the bowl. The outer edges of these flanges are straight as shown in Figure 3, so that they may be clamped by said washers 16 when in -various positions of adjustment toward or from the bowl. Preferably the top edge of the nozzle should project a slight distance beyond the opening in the top of the bowl as clearly shown in Figure 1.

For the purpose of automatically starting the motor 23 when' the seat is occupied. I have provided on the hinged seat 13 a flexible cushion 27 and electrical contact points 28 and 29 are secured respectively to the seat 13 and the bowl 10, and

connected by wires 30 with the electric motor, so

that when a weight is placed upon the seat 13. the cushion 27 will be compressed far enough to permit contact between the contact points 28 and 29,

thereby establishing a current through the wires 30 to start the motor 23.

In practical, use with the form of the invention a narrow slot with the top edge of the nozzle` projecting over the bottom edge thereof, the body of the nozzle being tapered inwardly and rearwardly and terminating in a rounded pipe member designed to be connected-to an air suction tube, thin flat metal flanges at the rear corners of the nozzle flush with the bottom of the nozzle and projected outwardly from the rear sides of the nozzle and having straight outer edges designed to enter between and pass under the ordinary hinge bolts of the toilet seat for adjustably clamping the deodorizer to the top of the bowl.
